Endevco® Model 7264D is a very low mass piezoresistive accelerometer weighing only 1 gram. This accelerometer is designed for crash testing, flutter testing, rough road testing and similar applications that require minimal mass loading and broad frequency response. This accelerometer meets SAEJ211 specifications for impact testing and the SAEJ2570 specification for anthromorphic testing. It is a direct replacement for Endevco Model 7264-2000 and 7264C, in that the location of the center of seismic mass is the same.
Model 7264D utilizes an advanced micromachined sensor which includes integral mechanical stops. This model has a high resonant frequency (>40 000 Hz) and frequency response, which captures more data and avoids spurious noise. The Model 7264D has minimum damping, thereby producing no phase shift over the useful frequency range.

Endevco® Model 7290A Microtron® accelerometer family utilizes unique variable capacitance microsensors. Accelerometers are designed for measurement of relatively low level acceleration in aerospace and automotive environments. Typical applications require measurement of whole body motion immediately after the accelerometer is subjected to a shock motion, and in the presence of severe vibrational inputs.
Gas damping and internal overrange stops enable the anisotropically-etched silicon microsensors to withstand high shock and acceleration loads.
Model 7290A can operate from 9.5 V to 18.0 V and provide a high level, low impedance output. The ±2 volt differential output is dc coupled at a dc bias of approximately 3.6 V. Frequency response is controlled by the near-critically damped sensors. The use of gas damping results in very small thermally-induced changes of frequency response.

• 0.2 grams
• Integral cable
• Adhesive mount
• High temperature

This ultra small vibration transducer (0.25 gram!)provides
virtual transparency applied to lightweight
structures, allied to relative freedom from strain
induced error. The reliability and performance
criteria applied to our transducers generally,
welded electrical connections and case seal, are
fully implemented in the construction of the
A/28/E.
Signal outlet is via a
surface contact socket.
A 0.8mm dia. softline cable is available
specifically for the A/28/E.
|
|
Micro-miniature triaxial vibration transducer comprising three shear plate. A/28/E inserts bonded orthogonally into a hard anodised aluminium housing.
The inserts are electrically insulated, individually and from the housing, thus
eliminating ground loop interference. The additional mechanical isolation implicit in the construction provides also near elimination of strain induced error.
The spatial response of a structure to dynamic forcing may lead to erroneous single axis vibration or shock measurement, due to the
inherent directional property of the transducer.
In cases where this is deemed to be a problem, an orthogonal three axis measurement, allowing computation of absolute value and direction offers a solution.

Description: The MiniSense 100 is a low cost cantilever-type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. Pins are designed for easy installation and are solderable. Horizontal and vertical mounting options are offered. The active sensor area is shielded for improved RFI/EMI rejection. Rugged, flexible PVDF sensing element withstands high shock overload. Sensor has excellent linearity and dynamic range, and may be used for detecting either continuous vibration or impacts. The mass may be modified to obtain alternative frequency response and sensitivity selection (consult factory). The MiniSense 100 acts as a cantilever-beam accelerometer. When the beam is mounted horizontally, acceleration in the vertical plane creates bending in the beam, due to the inertia of the mass at the tip of the beam. Strain in the beam creates a piezoelectric response, which may be detected as a charge or voltage output across the electrodes of the sensor. The sensor may be used to detect either continuous or impulsive vibration or impacts. For excitation frequencies below the resonant frequency of the sensor, the device produces a linear output governed by the "baseline" sensitivity. The sensitivity at resonance is significantly higher. Impacts containing high frequency components will excite the resonance fre-quency, as shown in the plot above (response of MiniSense 100 to a single half-sine impulse at 100 Hz, of amplitude 0.9 g). The ability of the sensor to detect low frequency motion is strongly influenced by the external electrical circuit.

VibraBoss 100 Vibration Monitor
A robust, versatile vibration sensor for continuous monitoring of rotating equipment such as large motors, fans, conveyors, etc. Simple to install and monitor; 2-wire hookup, 10-30VDC supply, signal powered, 4-20mA analog output proportional to average vibration velocity, or optionally, displacement. Designed for monitoring equipment with rotational speeds between 200 and 2000 RPM. For rotor speeds less than 500 rpm, "displacement" is generally more significant; at speeds about 2000 RPM, "acceleration" is the parameter of choice.
A unique and important feature of the VibraBoss 100 is that it responds to "jerk" - technically the third derivative of displacement with respect to time (y''') - rather than acceleration (y''). This makes it uniquely insensitive to the earth's gravitational field, thus simplifying installation by avoiding precise alignment usually needed for other acceleration (y'') based transducers. The electronics contained in the VibraBoss*100 integrates the jerk (y''') signal and generates the desired velocity (y' ) or displacement (y) output as a 4-20mA signal. The 4-20mA signal can be monitored externally with any computer monitoring system, chart recorder, or by an optional stand alone threshold detector. Typically, an increase in the vibration signal to 0.25 in/sec can trigger a maintenance alarm, while a level of 0.5 in/sec can initiate automatic shutdown.
For security, install one sensor horizontally at each bearing. A control box with power supply, set-point relays, meter, warning strobe and alarm horn for monitoring one or more points can be supplied.
